Calcium oxalate can not be absorbed and utilized by the human body, which will interfere with the absorption of calcium, and then lead to cramps caused by calcium deficiency.

The calcium content in water spinach is extremely high, which is 12 times that of tomatoes, and the calcium content in water spinach per 100 g is 99 mg.

On the contrary, eating spinach can supplement calcium.
